Experts raise concerns as US reports first human bird flu death

A US patient hospitalised with H5N1 bird flu has died, the Louisiana Department of Health said on Jan 6, marking the country's first reported human death from the virus.

The patient, who has not been identified, was hospitalised with the virus on Dec 18 after exposure to a combination of backyard chickens and wild birds, Louisiana health officials had said.

The patient was over the age of 65 and had underlying medical conditions, officials said, putting the patient at higher risk for serious disease.

Nearly 70 people in the US have contracted bird flu since April, most of them farm workers, as the virus has circulated among poultry flocks and dairy herds, according to the US Centres for Disease Control and Prevention (CDC).

Federal and state officials have said the risk to the general public remains low.
